Paper stock types are used for various grades in paper production and publication manufacturing. The stock types mainly connect with the various purposes the paper is encouraged in its end use. The most population will only encounter any stock types concurrently with an activity their works but will stumble upon many of the possible choices in time to time growth.

Grammage

 Grammage is outlined as grams per square meter (g/m2). Accordingly, the heaviness of a sole page of A0 paper outlines the grammage of that paper type as the A0 content is described by ISO 216 as bearing an extent of 1 square meter. An A0 page of 80gsm paper will consider 80 grams, an A0 page of 100gsm paper will contemplate 100 grams, and so forth. 

Basis Weight 

Basis load is a much earlier practice for outlining the load of paper. It was usual in the UK, Europe, and North America, where it is still used, just before the worldwide standardization of paper sizes by ISO 216 and allure public ancestors in European nations. 

Basis load is outlined as the burden of a heap of the complete paper in pounds (lb) (Note: the # is frequently used lb alternatively when referring to action weights).

There are various types of complete paper; those similarly used for the result of work paper and sheet are Bond Stock, Cover Stock, and Index Stock. The word Stock is frequently discontinued when referring to the various types of paper in their full-cut sizes.

Thus if you have a page of 20lb Bond Letter paper, it will be the regular width as 20lb Bond Legal, even though two together sheets will contemplate various amounts by way of the distinctness in length. However, a page of 28lb Bond Letter amount paper would not go along with a page of 28lb Cover Letter content paper as the full sizes for Bond and Cover are diverse. 

The newspaper has its own stock type, Newsprint, that measures 24” x 36” in complete breadth. This is much taller than the Bond and Cover full sizes, so the ultimate ordinary 30lb Newsprint is a much finer paper than a 20lb bond.
